A Method of Correcting Near-Infrared Spectra for Telluric Absorption

Abstract

We present a method for correcting near-infrared medium-resolution spectra for telluric absorption. The method makes use of a spectrum of an A0V star, observed near in time and close in airmass to the target object, and a high-resolution model of Vega, to construct a telluric correction spectrum that is free of stellar absorption features. The technique was designed specifically to perform telluric corrections on spectra obtained with SpeX, a 0.8-5.5 micron, medium-resolution cross-dispersed spectrograph at the NASA Infrared Telescope Facility, and uses the fact that for medium resolutions there exist spectral regions uncontaminated by atmospheric absorption lines. However, it is also applicable (in a somewhat modified form) to spectra obtained with other near-infrared spectrographs. An IDL-based code that carries out the procedures is available for downloading via the World Wide Web from the IRTF website.

39 pages, 10 figures, To appear in the Feb 2003 issue of PASP; IDL source code, as well as full resolution versions of the figures, are available at http://irtfweb.ifa.hawaii.edu/Facility/spex/
